Muscle-specific kinase (MuSK) myasthenia gravis (MG) is a neuromuscular autoimmune disease belonging to a growing group of IgG4 autoimmune diseases (IgG4-AIDs), in which the majority of pathogenic autoantibodies are of...
Conclusion: Although serum IgG4 levels are slightly increased, the levels do not support ubiquitous IgG4 responses in MuSK MG patients as the underlying cause of dominant IgG4 MuSK antibodies.
A Case Report and 31-Case Study: Does Takotsubo Cardiomyopathy in Myasthenia Gravis Patients Have a High Mortality Rate?
Myasthenia gravis is an autoimmune disorder in which antibodies are formed against post-synaptic nicotinic acetylcholine receptors that lead to impeded muscle contraction and commonly affects the oculomotor muscles. Takotsubo cardiomyopathy...
Relevance: We present a 66-year-old Caucasian male with a history of ocular myasthenia gravis who presented in a myasthenic crisis that was later diagnosed to have features suggestive of takotsubo cardiomyopathy.
A review of surgical management of progressive myogenic ptosis

ABSTRACT Surgical correction of myogenic ptosis is a sophisticated endeavor, as the disease is progressive and the post-operative course is prone to significant complications. We sought to review the literature...
Conclusion: Like surgical repair for other forms of ptosis, correction of progressive myogenic ptosis is guided by levator excursion. However, myogenic ptosis is especially challenging as it is characterized by worsening ptosis and the loss of protective corneal mechanisms. The goals of care with myogenic ptosis involves repairing ptosis just...
Editorial: Phenotypes of myasthenia gravis

(4~34.5) months after disease onset were reported in a study of 86 MG patients. Early-onset MG and precipitating respiratory infection were found as independent risk factors for progression to myasthenic...
Relevance: This special topic, including 13 original research articles, two brief research reports, two reviews, and one opinion article, all relevant to the above-mentioned phenotypic characteristics, contributes to an improved understanding and assessment of MG phenotypes.
